Received the 3/8" * 0.065" tubing I needed to make the tailwheel linkage. I'm using 5/16" Heim joints bolted to the wheel and rudder so I needed to tap the tubing to take the screw threads on the joints. As always with tapping its lots of oil half a turn in then quarter back and repeat until done. The result works well with the ability to adjust the length of the rod to get the wheel and rudder directly in-line. Lock nuts are used on the screw threads to avoid any chance of the linkage coming undone
